JOHN MANUEL, OF PHILADELPHIA, PENNSYLVANIA.

INDICATOR FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 235,545, dated December 14, 1880,

Application filed May 5, 1880. (No model.)

To all whom it may concern Be it known that 1, JOHN MANUEL, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Gas Burners, Measurers, Indicators, or Gages, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure l is a front viewof the indicator or gage embodying my invention. Fig. 2 is a side elevation thereof.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists of an attachment to the service-cock of a gas-pipe, whereby the pressure or flow of the gas may be regulated, adjusted, or controlled relatively to the number of burners required to be used and the quantity of gas consumed in a measure ascertained, or the number of burners in use may at any time be indicated. For this purpose I employ a'quadrant removably fitted to the barrel of the service-cock and a wrench with index-finger or pointer removably fitted to the plug of the cock, it being noticed that the quadrant and lever are applicable to cocks in use without requiring any special construction thereof.

Referring to the drawings, A represents a meter or service cock, which is of usual form and construction.

B represents a quadrant or sector, the upper end of which has an opening or boss, a, which is adapted to be fitted on the end of the barrel 1) of the cock, and provided with set-screws 0, so as to be securely connected to said barrel.

0 represents a wrench or key, having at its upper end an opening or boss, (I, which is adapted to be fitted on the end of the plug 0 of the cock A, and provided with a set screw or screws, f, and having at or near its lower end an index-finger or pointer, g, which is so disposed in relation to the quadrant B that it will sweep over the graduations of the latter.

It will be seen that when the parts are applied in position and the lever G is moved the plug 0 is turned, and may thus be opened to full or partial extent or entirely closed, the effect of which is to regulate, adjust, or control the pressure or flow of the gas.

In practice, the sector or quadrant is graduated from zero up to the full capacity of the service-cock, the graduations or numbers being marked by delicate adjustment and measured calculations for measuring the number of gas-burners in general use or the number of burners that may from time to time be added.

It will also be seen that as the pressure or flow of the gas may be regulated relatively to the number of burners gas may be saved; and, furthermore, the device provides in a measure a check upon the reading of the dial of the meter.

It will further be seen that the quadrant and lever may be applied to cocks in general use without specially constructing the latter, as there is a uniformity in casting cocks, and said quadrant and lever may be removed by slipping them from the barrel and plug, respectively, the screw first being loosened.

I am aware that registers formed of graduated arcs and index-arms have been applied to dampers and other valves, and so disclaim the same broadly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

As a new article of manufacture, the hereindescribed gas-burner indicator or gage, consistin g of the removable sector or quadrant B, with opening or boss a and set-screws c, and the removable wrenchlever O, with opening or boss (I, set-screws f, and index g, substan' tially as and for the purpose set forth.

JOHN MANUEL.
